Your air conditioning system is truly a marvel of engineering. It uses very complex rules of physics to move heat out of your home and keep you comfortable. Here at Cooper Climate Control, we’ve been providing quality Valley Metro air conditioning services for many years. We often get asked about how air conditioning systems work. One question that we wanted to address here was why there are two separate units for your AC system: one inside and one outside. We thought we’d shed some light on this for our customers to help them better understand how their air conditioner works.
Central Air Conditioning aka The Split System
When you talk about a central AC system or a heat pump, you’re really referring to a split system. It’s called “split” because there is one unit inside and one unit outside.
The Inside Unit
The piece of equipment inside your home is often referred to as an evaporator because it contains and evaporator coil. It also contains a fan and a fan motor that pushes warm air from your home over the cool evaporator coils. The evaporator coils absorbs heat out of the air, thus cooling it, and the fan pushes the air on through your ductwork and into your home.
But what happens to the heat that the evaporator coils absorbed?
The Outdoor Unit
The evaporator coils are filled with a refrigerant that acts as the courier for the heat. It circulates outside to the condensing unit. It is so-named because it contains and condensing coil. Like the inside unit, it also contains a fan and a fan motor. The fan blows outside air over the condensing coil which exhausts the heat into the outdoor air.
Once the refrigerant is rid of its heat, a compressor in the outdoor unit compresses the refrigerant very tightly and then circulates it back to the evaporator coil inside and the process starts all over again.
Common Air Conditioning Repairs
Now that you know a little about the air conditioning system in your home, you might be able to identify the cause of some common problems. For example, if you notice that your AC is producing just barely any cool air, it could be that the fan in your evaporator unit isn’t working well. Also, if your home isn’t getting cool enough it could be that you have low refrigerant levels or that the compressor isn’t work.
